i need help with triangles ( geometry)?

Question

i do not understand how to tell the difference between sss, and sas congruence postulate and the other ones. How can you tell what a triangle is? I don't understandddd.

also, how do you do proofs?.

please helpp / contact mee aim- bhattisweetie2
thankss.

Answer 1

SSS = side-side-side.

If two triangle have the same side measurements (say they both are 3-4-5, then they are congruent. The reason is that knowing the measurement of the sides means there is only one choice for the measurement of the angles.

SAS = side-angle-side

If two sides and the angle between are the same, then the triangles are congruent. If two triangles have sides of 3 and 4, with 90 degrees between, they would have to be congruent.

Order is important. If you said SSA, that means two sides and the angle adjacent to only one of them. This would not force the triangles to be congruent.

In summary:
SSS does
SAS does
ASA does
SAA (or AAS) does

AAA does not
SSA (or the reverse, which I can't spell) does not

Answer 2

I bear in mind that there is a thorem that if the two factors of a traingle are equivalent then the attitude opposite to them additionally are comparable. Please see the thorem. So the bisectors make a isoscele traingle with the factor in between the angles have been getting bisected.i'm going to later write you the evidence of the theorm. because of the fact the each a million/2 of the angles are equivalent, then the entire angles are equivalent. here you stumbled on the two angles are equivalent. As consistent with definition: in a traingle if the two angles are equivalent, then that traingle is talked approximately as a isoscele traingle.

Answer 3

practice practice practice. if you have specific questions then post those but this is a rather encompassing question so I think the best advice is to tell you to work on lots of problems until you understand the logic
